The Evolution Of Cutting Tools

New Mind - 2020-01-31

The story begins with how cutting tools evolved from simple paleolithic stone edges to the knives, axes and other basic metal cuttings tools via the copper, bronze, and iron age. From there we look at the discoveries of metallurgy during the industrial era, the rise of steel, and the evolution of machine tools. We explore the advancements of the tooling mills, lathes and shapers used as cutting tool materials moved from high-speed steel to carbides, and other exotic cutting materials.

@Steven Kelby which is why i used quotation marks around "iron" :) but thanks for the clarification.

Steven Kelby - 2020-02-15

@Dixie_rekd Oh yep, makes sense 👍

Joey Cook - 2020-03-07

I always thought carbon was intentionally added to iron to make steel. I had to crawl through a few hours of frustrating research to unconfuse myself.

Just finishing my Mechanical Engineering degree. Amazing video! It's a very good review of material engineering and heat treatment process.

Warped Perception - 2020-02-01

If you ever need footage for your videos (free of charge) just shoot me a message, I have huge libraries of world class footage... Love your videos 😍❤️!

New Mind - 2020-02-03

Thanks so much, world class you say 🤔 I might just take you up on that offer

Warped Perception - 2020-02-06

@New Mind  @New Mind  oh yeah !. Obviously that depends on the subject, I won't have everything. But my viewer request is "the history of the catalytic converter" I honestly had no idea that the catalytic converter was such a big subject, oh man do I wish I had enough time to research and learn about the history, Why it was invented, where it all started, and where it is today. After doing that episode on my Channel I quickly realized how we are in 2020 and we're still blowing about 80% of the energy of a gallon of gasoline right out of the tailpipe, and in the case of the catalytic converter, the catalytic converter is with burning most of that energy to reduce emissions, something's got to change soon, that's a lot of energy being dumped.

@Warped Perception but its eco cuse its being reduced in cat... thats most "funny" part for me

Memorabilia Temporarium - 2020-01-31

I don't stress this enough: there are only a handful of channels that I know within YouTube that rival yours.

Tonatiuh Mellado - 2020-02-01

I agree

Ethan Zhu - 2020-02-03

This is the first channel that I am willing to turn notifications on for

aurora2319 - 2020-02-15

I concur I reckon that he's in the same league as the acclaimed "Real Engineering" channel

Person Man Man - 2020-02-17

What are those handful channels?

electriccat - 2020-12-31

name three! thanks! :)

Warped Perception - 2020-02-01

Cutting tools are part of my life everyday, everywhere Oh Yeah!

david mendoza - 2020-09-11

love your vids there nice to watch after school :)

Mik - 2021-01-05

When you are pressured to comment on everything to advertise your channel but you don’t have anything meaningful to say...

L - 2021-07-19

@Mik nailed it.

Robin Hodgkinson - 2020-02-01

Anyone interested in engineering must read “Exactly: How precision engineers created the modern world”. This book covers the history of engineering - the famous names, tools and techniques that enabled ever increasing levels of precision and standardisation, and gives real insight into how the Industrial Revolution brought us to the modern world we live in today. A journey from the 18th century blacksmith to GPS atomic clocks. Highly recommended!!

Robin Hodgkinson - 2020-02-10

Well John for someone who’s not going to debate me that was a pretty long reply...
But we agree on one thing - neither of us is going to change our mind and I was under no illusion I would - your first comment kinda gave that away... Anyway it’s all just internet piss and wind on both our accounts. I’m sure not going to change the world and neither are you.

But I have to call you out on at least one glaring factual error. Claiming that life expectancy is lower today is just plain rubbish. Improvements in sanitation, medicine and diet have raised life expectancy considerably for billions of people in the last century. Life expectancy is higher than it ever was and you don’t have to look far on Google or wherever, to verify that fact. Claiming the opposite totally undermines the credibility of your argument. It’s just BS. Plain and simple.

And one last thing. Be wary of how you use Google. It will show you whatever you search for. A better echo chamber there never was.

Over and out.

John Bloom - 2020-02-10

@Robin Hodgkinson Life expectancy is higher now, that I do admit. But the general of health of people is lower in the modern world due to the processed industrialized diets. Obesity is at an all time high while it was extremely rare for someone to be obese pre industrial revolution. I don't know why I posted that people lived longer back 100 years+ ago, that was an error on my part. Now a days we have triple bypasses, blood pressure pills, and insulin to keep people living longer even if they are unhealthly.

Jonas - 2020-02-16

@John Bloom I think you could agree on a point that was already made by Robin, the Problems you are stating are hardly "technologies" fault, but societies.

John Bloom - 2020-02-16

@Jonas Well the problem is that people think that technology is the answer to all of our problems due to greed, ignorance, and delusion. If people had access to technology that will be available 300 years from now than they would leave all jobs, careers, and skills up to automation and that would be one sad boring world to live in.

AIon - 2020-12-11

I need technology to escape people like you mr john. But just realize the following.. since it can rely work. If you wanna go back to good old days.. now is a better time then ever. Pick your phone (ironical i know) and 2000 dolars and go to a third word country right now. Call a few people to join you. A few will come. You need the phone and a starlink connection to learn shit since without you not gonna be able to do much. Go build a hippy eco village from cob and straw and stuff where you can blacksmith and have a job the way you want. Be happy. Waste your life on following the bullshit hedonic coctail you are a slave to. At least attempt to be .. cause we know how well that works when a venomous snake bites you by the cock and then you need advanced medicine to keep you going. But dont worry with robots ai and shit we can do surgery on your cock from 12000 km away from another continent. Remote surgery. All you need to do is keep showing your lives like vlogs and such. To see how the hippie experiment is going. Ill come at times to visit.. maybe forge a pair of horse shoes just to remember what real life feels like. In critical situations where you rely need technolgoy we can bail you out with out devolution based technology .. if you want of course. If no just die with extreme cock pain, or malaria or something. So yeah.. like im telling you.. there was never a time in history you had this options.. not even the emperor of rome or persia or the china guy had so much capabilities like you do now. Try it. Why not? Go live what you preach.

you should add "15:40 Worst drilling job you'll ever see"

FrankieJames7 - 2020-02-02

I am a ballistic engineer, and when i first learned why metal is so strong it was compared to paper. if you have a solid sheet of paper and apply force to it, it will rip, and the rip will continue all the way to the other side with little effort. now take the same material, paper, cut it into strands, and weave those strands together perpendicularly, if you rip that paper the rip will get stopped at the strand boundary/separation. I've never seen footage of this tangling effect on real metal grains. that was really cool how you showed grains shifting under stress

kindlin - 2020-02-03

I also hadn't seen actual grains undergo plastic deformation. I would love to see a lot more of it. Also, that paper analogy is pretty good.

suibora par - 2020-01-31

Top tier content my dude. Suggestion: timestamps for the different sections would be great for longer videos

steelcannibal - 2020-01-31

Watching this between cycles in a machine shop! Love your videos man! I've never seen video of the crystalline change in metals before that was a trip!
Keep up the great work!

Hey It's Drew - 2020-01-31

this old Tony does a good video about cutting tools for lathes. start with a block of metal and grinding it until it's just right, explaining each and every angle as he goes from. a square

Clockworkfish - 2020-02-01

Wow, this is an incredible piece of work! It's so rare to find such densely informative content that's actually enjoyable to watch these days! Thank you for making this!

New Mind - 2020-02-03

Thank you for the kind words.

j master - 2020-02-01

Well done on the research for this video. You took on some fairly complex material science and summarized it nicely. Better than any other channel in this category!

Enzo P - 2020-02-02

I had so many "Ohhhhhh yeah, now I get it!" moments in this video. you very clearly explained several metallurgical concepts that I never fully understood. Thank you!!

iTeerRex - 2020-01-31

A high quality documentary on the history of a great topic. Thank you.

Steven Parin - 2020-08-28

Filled with metallurgical misinformation,. Stoneworking too.

Eric Pratt - 2020-02-04

My favorite part is how in depth you go into everything. That's what I look forward to! I watched this thinking it would be a brief overview of the timeline of milestones in cutting tools. It was wonderful to learn more about the process of hardening and why things are the way they are. I can always count on an educational video. I don't care if these videos take a long time to come out as long as they maintain a quality like this one.

New Mind - 2020-02-04

Thank you for the motivational words! It’s very much appreciated

Real name - 2020-02-01

It brings me great joy to have known about your channel. It is without doubt a channel that will grow to surpass the famous engineering YouTube's in the coming months. The content quality is amazing and in detail. As a mechanical engineer I find your work to be extremely interesting for a non engineer. Keep up the good work and may god bless you

Tyler - 2020-01-31

I have never heard cast iron be called "low carbon" before. It has a carbon content above 2% and contains graphite flakes within the metal matrix.

Ben Spierings - 2020-02-01

maybe a low carbon cast iron, which would indeed be high carbon compared to a steel?

but since the context was cast iron he just stuck with low carbon in that reference frame

Anders Juel Jensen - 2020-02-04

It was low carbon compared to its predecessors, so in the context given (chronological history of development) the statement was correct.... but I did a double take on it too :P

Curtis - 2020-02-05

A "lower" carbon content would have been a better way of putting it

Bingo Sun Noon - 2021-06-11

Ductile Iron, used for pipes and machine tools.

August Von Mackensen - 2020-02-02

How things change, back then it was an achievement to get 1.5mm accuracy on 1000mm dia.
Step by step, these days a roughing cut is 10 times more accurate.
Great video btw !

vondeliusc - 2020-09-05

As a machinist growing in experience, this was SUPER interesting. Thank you!

Nax FM - 2020-02-01

Keep this great quality and you will be famous like real engineering and Wendover in no time.
Been subscribed since you had about 10.000 subscribers, and you are already at 150k!
This channel is growing fast and it deserves it!

New Mind - 2020-02-01

Thank you! And thanks for the early support.

Zephyrus Morley - 2020-02-01

Wow. I am blown away at your vast knowledge of the subject. Such good information.

Also wonderful video production. The selection of vids and pics for visual aid helped a lot. And the layout of the video is also logical and easy to follow. Doing a historical time line and alloys, then touching on lasers and 3D printing. The subject was well covered.

Thank you for the education and entertainment. You are a pro.

Ron Roberts - 2020-02-01

I've seen several videos like this, and this particular one is the best by far. As the saying goes, the best tutorial is like a skirt. Short enough that it's not boring, and just long enough to cover the important bits...well done, sir.

ba doem - 2020-02-02

Lol ☺️

massivejester - 2020-02-02

This channel is one of the best and most underrared on youtube. Consise, informative, good narrator and to the point without having any clickbait.

Mrwrenchifi - 2020-02-01

I feel like I'm watching a summary on the year long metallurgy course I took. Well done getting all this information in such a small video.

CatNolara - 2020-08-28

7:55 I spotted an error there: cast iro has actually more carbon than all steels. It's so much that the carbon can't stay in solution and forms small graphite grains, which give the cast iron its properties (self lubrication, brittleness, good dampening of vibrations).
Pure iron however, with no or only a little carbon, is pretty soft and malluable.

Vishank - 2020-07-03

This is such a masterpiece! Looking forward to more of your content bud! Keep rollin!😄💎👌

Colin Gantiglew - 2021-07-14

I've just learned as much in 22 minutes that I knew from previous decades. Thank you!

axelbender1 - 2020-02-21

excellent video, I'd add cutting with high pressure water stream, though It's the same non-mecanic approach as plasma/laser cutters

Tabletop Machine Shop - 2020-02-01

Awesome video! I've often wondered how one could explain dislocation theory quickly and simply and you did an amazing job!

Your educational skills are top tier man, keep em coming!

Prophet's Space Engineering - 2020-02-13

Damn! Now that is some high-quality stuff. You do a pretty great job of explaining these techniques. Having gone through years of education in this field, the serious scarcity of quality video footage was very noticeable... This stuff definitely rivals a lot of the educational material I was shown during my training. This would make a fine introduction video for several fields and jobs. Very impressive.

Oliver Rivett-Carnac - 2020-02-03

Fantastic video btw, never learnt so much in so little time.👍

Hello - 2020-02-01

so interesting. Love your videos. Thought you wont go ino depth of the metals but more into how cutting works etc but this is great, very cool, especially with the history timeline
